Do you know why the size of the universe by the inflation model is commonly ignored in popularizations? Is it that the size of the universe out to the visible limit is already incomprehensible and considering the whole universe beyond that would short-circuit most minds?
But string theory doesn't enter into that. Essentially all of the structure spectrum of the CMBR is determined by the fact that energy transport was primarily acoustic.
The Big Bang theory can work with or without string theory.

For one thing, we only just recently determined that the universe is very, very much larger than the observable Hubble volume. For another, if a writer restricts his comments to our Hubble volume, it is at least possible to talk accurately and provably. And after all, our Hubble volume is quite large enough to blow almost any mind that tries seriously to grasp it.
